The objective of this study was to investigate the reliability, feasibility and analytical impact of home-based measurement of forced vital capacity (FVC) and dyspnoea as clinical endpoints in idiopathic pulmonary fibrosis (IPF).Patients with IPF performed weekly home-based assessment of FVC and dyspnoea using a mobile hand-held spirometer and self-administered dyspnoea questionnaires. Weekly variability in FVC and dyspnoea was estimated, and sample sizes were simulated for a hypothetical 24-week clinical trial using either traditional office-based interval measurement or mobile weekly assessment...

OBJECTIVE: Nasal obstruction and oral breathing may play an important role in the pathophysiology of obstructive sleep apnea (OSA). This study aims to better understand the link between oral breathing, nasal obstruction, and the spectrum of sleep-disordered breathing. STUDY DESIGN: Prospective study. METHODS AND MATERIALS: Prospective study of patients who presented to the Otolaryngology clinic and underwent polysomnogram (PSG) from 2015 to 2016...

INTRODUCTION: The change in body position can alter pulmonary functions parameters, therefore it is important to understand the physiological basis of these alteration. Ideally, spirometry is done in sitting position until the subject is unable to do so. Hospitalized patients often assume recumbent body positions irrespective of underlying pathology. Hence, need arises to find out best recumbent body positions for the benefit of these patients to make breathing comfortable for them. AIM: The aim of this study was to find out whether the change from the supine position to crook lying and Fowler's position (45° dorsal elevation) causes change in spirometric parameters...

STUDY OBJECTIVES: As lung volume decreases radial traction on the upper airway is reduced, making it more collapsible. The purpose of this study was to measure change in end-expiratory lung volume (EELV) following sleep onset and to evaluate the relationship between change in EELV and sleep-disordered breathing. METHODS: Twenty subjects underwent overnight polysomnography, of whom 14 (70%) had obstructive sleep apnea (OSA). Change in EELV was measured throughout the night using magnetometry...

To evaluate the association between prenatal and postnatal exposure to pet ownership and lung function in children, a cross-sectional study named Seven Northeastern Cities (SNEC) study was conducted. In this study, children's lung function including the forced expiratory volume in 1 second (FEV1 ), forced vital capacity (FVC), maximal mid-expiratory flow (MMEF), peak expiratory flow (PEF) were measured by spirometers, and pet ownership situations was collected by questionnaire. Analyzed by multiple logistic regression and generalized linear modeling, we found that for all subjects, pet exposure in the first 2 years of life was significantly associated with lung function impairment of FVC<85% predicted (adjusted odds ratio [aOR]=1...

Forced spirometry testing is gradually becoming available across different healthcare tiers including primary care. It has been demonstrated in earlier work that commercially available spirometers are not fully able to assure the quality of individual spirometry manoeuvres. Thus a need to expand the availability of high quality spirometry assessment beyond specialist pulmonary centres has arisen. In this work we propose a method to select and optimise a classifier using supervised learning techniques by learning from previously classified forced spirometry tests from a group of experts...

BACKGROUND: Transversus abdominis plane (TAP) block is useful in reducing post-operative pain in laparoscopic nephrectomy compared to placebo. The purpose of this work is to compare post-operative pain and recovery after TAP block or trocar site infiltration (TSI) in this surgery. METHODS: A prospective, single blinded study on patients scheduled for laparoscopic nephrectomy. Patients were assigned to two groups: TSI Group: trocar site infiltration at the end of surgery; TAP Group: unilateral ultrasound-guided TAP block after induction...

Continuous monitoring of respiratory patterns and physical activity levels can be useful for remote health management of patients with conditions such as heart disease and chronic obstructive pulmonary disease. In a clinical setting, spirometers serve as the gold standard for monitoring respiratory patterns such as breathing rate and changes in lung volume. However, direct measurements using a spirometer requires placement of a sensor in the patient's airway and is thus infeasible for continuous monitoring in nonclinical, ambulatory settings...

INTRODUCTION: Hypothyroidism is a silent epidemic of our times. In India, the prevalence of hypothyroidism is 11%. The effect of hypothyroidism on respiratory system is debatable with studies suggesting both obstructive and restrictive disease patterns. The symptoms range from mild dyspnoea to life-threatening respiratory failure. This study emphasizes the effect of hypothyroidism on dynamic respiratory functions. AIM: To find out the changes in dynamic respiratory functions (FVC, FEV1, FEV1% and PEFR) in both male and female hypothyroid patients within age group of 18-45 years...

BACKGROUND: Cigarette smoking is a widespread social habit in Nigeria with extensive deleterious multisystemic effect. Ventilatory dysfunction is one of the cigarette smoking-related illnesses that affect the respiratory system. Spirometry is an investigative method that can be used for the early detection of ventilatory dysfunction even before the onset of the symptoms. SUBJECTS AND METHODS: A questionnaire adapted from the European Community Respiratory Health Survey was administered to collect demographic, clinical, and cigarette smoking data...

Peak flow meter with questionnaire and mini-spirometer are considered as alternative tools to spirometry for screening of asthma and chronic obstructive pulmonary disease. However, the accuracy of these tools together, in clinical settings for disease diagnosis, has not been studied. Two hundred consecutive patients with respiratory complaints answered a short symptom questionnaire and performed peak expiratory flow measurements, standard spirometry with Koko spirometer and mini-spirometry (COPD-6). Spirometry was repeated after bronchodilation...

Spirometry is a physiological test for assessing the functional aspect of the lungs using an objective indicator to measure the maximum amount of air that a patient can inhale and exhale. Acceptable spirometry testing needs to be conducted three times by an acceptable and reproducible method for determining forced vital capacity (FVC). Until the results of three tests meet the criteria of reproducibility, the test should be repeated up to eight times. Interpretation of spirometry should be clear, concise, and informative...

Obese people have higher risk of respiratory symptoms. The relationship between obesity and lung function varies with age, race, and geographical region. The objective of this study is to examine the effects of body mass index on spirometric tests among adults in Xi'an city.This is a cross-sectional study. Pulmonary function testing was conducted on participants recruited from Xi'an, China between July and August 2012. Force expiratory volume in first second (FEV1), force vital capacity (FVC), FEV1/FVC, peak expiratory flow (PEF), and forced expiratory flow at 25-75% (FEF25-75) were measured by portable Spirometer...
